Press the menu in the upper right corner
Under departments you can see the departments you use. Eg. Marketing, Sales, Support etc.
If you want to delete one or more departments, select these and click on the trash can.
If you want to change departments, select the department you want to change, and then change the information in the right column (name and department number).
If you want to add more departments, click + and fill in the name and department number.
However, be aware that departments created / changed in edilion will not sync with your ERP and will disappear if you click Import. It is therefore recommended to create / modify everything in your ERP and import it into edilion afterwards instead of vise versa.
Remember to press SAVE so that the chart of accounts is updated
